摘 要:徐矿集团哈密大南湖五号井首采工作面1801运输顺槽和回风顺槽顶板含砾粗砂岩含水层的存在,巷道顶板常出现淋水现象,造成了巷道支护困难,水对顶板、支护体、支护材料的弱化。锚杆、锚索支护与喷浆、架棚形成了很好的互补作用,两者的力学特性有机地结合,达到了控制巷道围岩大变形的目的。使用锚杆联合支护,加强了巷道的支护强度,使巷道围岩基本稳定,能保持巷道的基本形态,为工作面的回采提供了保障。通过对综合矿压站观测数据的分析,掌握巷道围岩矿压显现规律,为该矿巷道支护设计最优化提供了参考。Due to the existence of gravel bearing coarse sandstone aquifer in the roof of 1801 transportation channel and return air channel in the first working face of Dananhu No.5 mine in Hami,Xuzhou Mining Group,the roof of the roadway is often flooded,resulting in the difficulty of roadway support and the weakening of water on the roof,support body and support materials.Bolt and anchor cable support and shotcreting and scaffolding form a good complementary role.Their mechanical characteristics are organically combined to control the large deformation of roadway surrounding rock.The use of bolt combined support strengthens the support strength of the roadway,makes the surrounding rock of the roadway basically stable,can maintain the basic shape of the roadway,and provides a guarantee for the mining of the working face.Through the analysis of the observation data of the comprehensive ground pressure station,the ground pressure behavior law of the surrounding rock of the roadway is mastered,which provides a reference for the optimization of the roadway supporting design of the mine.
